According in ini' invention the throttling nl' the str-:iin is direted hy means of one or \vwral sete. of nozzles haringv suitable shapes :niti iliinrnsiona. :ind distributed in suitable positions; idoli;r dir inziin Apipe of a steam piani heini-cn the hoilcr and the place of vonmnnplion.. Said nozzles areconstru-cted in the. shapiof a truncated cone havingthe \.nnill hastslig'htly liariiig.

.\frording to my. invention the stcain'is aimed to enter into the nozzles through the larger hase of the conc; thcnozzles are,

The. apertures -10-, pro-- vided inthe cylindrical piston 4 are so disposed as to successively expose each rowo nozzles while piston -lis', displaced.

The pistons -4 and -5 are siinulteneously moved in such a way that the size of the passage of the steanrfroin thechan'iher l into the chamber F will be proportioned to the lnumber of'open nozzles.

Fig. B-shows the application of my invention to :in ordinary double seat valve. This '\'alrc is.'providedV with a cylindrical piston -l-, adapted to fslideA on the internal sur.- face of the casing -2-, which has a numher of apertures cut lin its cylindrical sur- 'lhe 'casing 2 is providedA with several sets of nozzles. The height of the apertures and the intervals between them are so proportioned as' to expose graduallyea'ch row of noz- Th'e valveV piston Fifi-'- of 'the double seatvalve is provided with a. flange adapted to hear; against the collar of piston -1` in any suitable \vay and in any suitable p osition, between the boiler and the place of consumption and it will bel understood that inail the constructions shown the steam by being caused to pass througlithe nozzlesprow vided in its path of fiow will be throttled and thereby made to give up its .moisture so thatz a dry or even a superheatedvsterm will be obtained.

Having now particularly described and ascertained the nature of my said invention .and in what manner the same is-to be performed, I declare that what I claim is:

1. In combination with a steam conduit, a set of nozzles havingthe shape of truncated cones mounted on said conduit with their .spacer-between the said two casings,

axes lying in the path of the lmving @wenn the nozzles with their wider buse projecting from Said Qtmdixit.

2. In combination 'with a steam Conduit, a set of nozzles having the shape of trnn cated cones with their smaller hase slightlyy flaring mounted on said conduit with their axes lying in the path of the flowing steunt the nozzles` with their wider hase project-ing from said Conduit. i

2S. ln eombilnition `with a steznn conduit`v a plurality of rowz` of nozzles mounted on said Conduit with their axes lying in the path of the flowing steaun und having the shape of truncated cones. with their wider port-ions projecting from said eonduit, und means for successively exposing said rows of nozzles.

4. ln combination with a steam conduit; and a steam valve located therein and com4 prising an outer and an inner easing spaced apart' from each other, u plurality of rows of nozzles mounted in said inner @ageing in the path of the low of the steam and shaved like truncated cones with their wider bese projecting 'from said inner cziSing into the ano an f igwrtnred valve in said inner cesing adapted to ence ssively expose the various rows of nozzle.

5. ln combination Wit-n a steam conduit nml e :einem valve located therein :ind comprising un outer miti an inner easing spaced apart from euch other, a. plurality of rows of now/.les mounted on seid inner casing in the path of the flow of the steam und shaped lilge truneziteil Cones with their wider buse projecting from said inner easing into the space between the will two 1ensingrs, an gipertureil mire in said inner easing adapted to soecessively expose the various rows of nozzles, und n vulve for controlling the admission of steam to the spaee between the Suid inner und outer raising, und means connecting said two vulves to ineure their simultzineoue` oir eration.

ln testimony whereof have signed my name to this epeeiliezition in present-.e of two subscribing witnesses.
